Does it happen at a specific time? Any error/warning related to a reboot in the Event Log?<br />
<br />
I would check Windows Update settings first.<br />
Settings -&gt; Update and Security -&gt; Windows Update -&gt; Change active hours and Restart options<br />
<br />
Then Local/Domain GPO -&gt; Computer Configuration -&gt; Administrative Templates -&gt; Windows Components -&gt; Windows Update -&gt; Configure Automatic Updates -&gt; check your settings

I would check Windows Update settings first.
Settings -> Update and Security -> Windows Update -> Change active hours and Restart options

Then Local/Domain GPO -> Computer Configuration -> Administrative Templates -> Windows Components -> Windows Update -> Configure Automatic Updates -> check your settings

Is the server all up to date?<br />
<br />
Before you find out the cause of the issue, a temp workaround might be to override the global monitor which is probably causing reboots. <br />

solved by changing CPUs and COREs :-)

I am just curious. What exactly did you change? Did you add CPUs and cores? Something else?

Hi Experts,

my exchange server 2016 restarts each night.
How to troubleshoot this ?
Where to look into ?

suddenly rebooted exchange server

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.

Windows 10

Microsoft Azure is a cloud computing platform and infrastructure for building, deploying and managing applications and services through datacenters. It provides both platform-as-a-service (PaaS) and infrastructure-as-a-service (IaaS) services and supports many different programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems. Cloud Services is a PaaS environment and can be used to create scalable applications and services; there are specific software development kits (SDKs) provided by Microsoft for Python, Java, Node.js and .NET. Azure also has file and storage services, data management, analytics and DNS services.

Windows Server 2016 is the successor to Windows Server 2012 R2. Built upon the same core code as Windows 10, Windows Server 2016 brings enhancements in security, servicing, and connectivity. A particular focus on this release was hybrid-cloud scenarios, and has close ties to Azure and other Microsoft cloud initiatives. This does not detract from the many improvements that are available for on-premises-only deployments

Windows Server 2016 comes in Datacenter, Standard, and Essentials editions, and for servicing, has adopted windows 10's cumulative model. The new nano-server install is designed to be remotely managed and is designed to be kept current through continuous feature updates. The full GUI install operates similarly to windows 10's "Long Term Servicing Branch" (LTSB) model with cumulative security updates.

Windows Server 2016 has also shifted from a per-processor-and-CAL licensing model to a per-core-and CAL licensing model. This brings Windows Server's licensing more in line with Microsoft's other products and makes hybrid-cloud license planning easier as well.
